SPIEGIFICATIQN forming part 0f Letters Patent N0. 682,522, daoed September 10, 1901.

Applioation filed May 27,1901. Se1ial N0. 62,109. (N0 model.)

T0 aZZ w7w7n it may c0ncern:

Be it; known that we, WILLIAM BOEKEL and JULIUS BOEKEL, citizens 0f the Unlted States, residing ab Philadelphia, in ehe countzy 0f Philadelphia and State of Pennsylvaniahave invented certain new and useful Improve ments in Sterilizer-Oases; and we do hereby deolare the following 130 be a full, 0lear, and exact description of the invention, such as Will enable others skilled in the art to which it appertains to make and use the sa1ne.

This invention relates to sterilizer-cases forsurgical instrument-s; and it oonsists in Ehe construonion and combination of parts hereinafte1 sei forth and claimed.

In ehe acoompanying drawings, Figure 1 represents a perspeotive view of nhe olosed case. Fig. 2 represents asirnilar view of the same When open. Fig. 3 represents a side elevation of Ehe Gase arranged for sterilizing, Lhe sectionsbeing separated and superposed; and Fig. 4 represents a detail view of the raek, the implements having been removed and ehe spring-eatch turned back.

The lower seeuion A of the case receives within it atightly-fitting removable frarne C, eonsisting of side bars 0 and cross-bars c, the latter being provided With notohes 0116- cesses 0 of Varying sizes for holding a se1; of surgical 01 other implements Whi0h are to be sterilized. In ehe presentinstance nhe franne is adapted t0 hold a vaecinalsion set of instruments and appurtenanoes, (markedDD D*") several additional noehes and reoesses being, however-, provided in oase other instrumencs should be substituted. As shown in Fig. 2, these instruments a1e held to 1ahe frame by a spring-oatch E, oonsisting of a resilient; tongue hinged or pivoted 130 one of the side bars C and engaging ab its tip a rigid Ing or hook F, raised 011 the other side bar 0f said frame, such engagement being effected by depressing the said tongue or catch upon the said instruments Wil3ll iahe said tip slightly bent laterally, so as 130 occupy a position ab the side of said lag, and then slipping it uncler the same, when its resilieney Will hold Ehe said tip upward against the said lug, free from any serious risk of accidenta1 dislodgment in ordinary oiroumstanees. The frame and its eontents a1*e easily removed together froxn the case as one piece and sirnilarly replaced lherein. When any 0f the instruments o1 arbioles am to be 1e moved, the catcl1 E is burned back into the positi0n shown in Fig. 4 after being disengaged f10n1 the said 111g 01 hook, 01 it is ab least raised suffieiently lo pern1it such 1'e* moval. In this way 0f course tl1e entire set 0f instruments may be removed and a new sei: substituted in the frame.

The upper seotion B of tl1e case is hinged to the lower sec tion on one side by a re1novable pintle I. It is also provided 011 its top With bosses H, whieh serve as feel; 0x support-s when the said 1sop beoomes the botton1 in the sterilizing position of nhe devioe illustrated by Fig. 3. This section is also provided wih a plate J, parallel to said top and 0011- verting Lhe greater part of the interior of said section B into an aloohol-tank. This plate J has a central screw-neck J 'receiving a screwcap K, whieh prevents the escape of the aloohol when the oase is not in use for sterilizing. A wire grating L extends aoross the opening of tl1is sorewmeck, holding in place a round wich or pad Z, of asloestos ber or'other Suitable oapillary 1naterial, adapting this seation B '00 be used as a small aloohol-stove when in he separated and inverted position shown by Fig. 3. The screw-cap being removed, wire supporns N 0f convenieno form am attaehed to the said plate J near its ends, being hinged to fold down upon the said screw-0ap and bent to rest thereon, as shown in Fig. 2, with as litle extension as possible of any part be- 10w the plane of ol1e same, when seeiaion B is folded on seotion A. to eomplete tl1e closing 0f the case in order thal; these folded supports N may not geb in the way of the frame or its contents. minal cross-loars n of the supports are not in Contact with ea0h other, bat leave a spaee 173 between thenn for the reception of the tongue or eateh E in this folded position of the oase. These Supports N have elbows N, which bear against t1he plate J when the said supports a1e turned upward, as shown in Fig. 3, said elbows preventing these supports from turning 1100 far outward and aouing as bases 01' braces therefor. The detached section A of the ease oontaining the frame C and the in- For the san1e reason the ter stru1nents fasened therein rests upon he rods 01 bars 12 of said supports dming the operation of sterilizing.

Any suit;able sterilizing solulion is poured into section A,the wiek Z 0f section B is li ghted, Ehe heat caused thereby vaporizes the said solution, andthis is eoninued unti1 the instruments are certainly sterilized. is then b1own out, the casing A removed from the supports N, the sorew-cap replaced, and ohe supporns folded down. If the instrumnts are needed at once, they are simply removed from the franne one by one 0x all together, either while the frame is Stil] in seetion A 01 after withdrawing it; therefrom, according to convenience. The seetions are placed side by side and the removable pin'nle aforesaid replaced in nhe hinge eonneeting Lhem. They are then folded together, and a spring-catch 0, attached t0 the inside 0f ehe front; 011 secbion A, engages the lip of seetion B, fastening the owo sections detachably together in front, and thus completing the e10 sure of the case. This device is easily transformed ab Will, as above indioated, froxn an instruments-case to a sterilizing stove and tray, and vice versa. Ibs material is preferably aluminium or other meta1nob easily oxidized. It is compaet, ligh, neat, and streng, easily and eheaply made, readily repaired, efficient, and d mahle. The catch 0 aforesaid is provided with the usua1 pressure-stud p, ext'ending 0ut through the front of section A, f0r opening ohe ease.

IIavingthus described our in vention, what The wick we elain1 as new, and desire t0 secure by Lettransforxned ab Will frorn an instrument-holding case 130 a sterilizing stove and tmy substantially as sei; for'h.

3. The section B provided with an internal plat'e J having a screw neck and a wiek 'forrned therein a-nd folding Supports N raised thereon which are provided w'ith elbows N serving as bmces therefor, in combination with section A adapted to re sb 011 said supports and serve as a tray, and a detachable eonnection belaween the sections, allowing them to be folded together, when connected, to c1ose the case, substantially as Set forth.

In tesbimony whereof we affix onr signatures in presence 0f two witnesses.
